Chimpanzees Adopt New Grunts to Communicate to New Neighbours

A latest research reveals that monkeys that migrate from one region to another change their vocal calls according to their surroundings. They adopt the newer call in order to communicate with new chimpanzees.

Researchers of University of New York observed a change in the vocal calls of chimpanzees that moved from Dutch zoo to Edinburgh. These animals were unable to produce an accent exactly similar to the Scottish brogue. However, they tried to alter their vocal calls in numerous ways.

Experts followed the chimps for a long time period of three years. The close analysis of their behavior demonstrates that these chimpanzees gradually adopted the sound and environment of new region. They learned the new sound after creating a strong bond with the local group.

Chimpanzees’ response towards food provides an evidence for the research. Generally, mandrills make sound and vocalize whenever they eat foods. In this case, the Edinburgh chimps developed a unique low pitched sound when they were offered apples.

Katie Slocombe, a psychologist of the University of New York discussed the entire report in detail. She informs that this is the first time when researchers witnessed such kind of behavior in chimpanzees. They have not observed any specie that changes sounds according to the environment.
